Some RNA molecules spend time in a restful state akin to hibernation rather than automatically carrying out their established job of delivering protein-building instructions in cells, new research suggests.

(Phys.org) -- For years, many scientists had thought that plate tectonics existed nowhere in our solar system but on Earth. Now, a UCLA scientist has discovered that the geological phenomenon, which involves the movement ...

Technology developed by Disney Research, Pittsburgh, makes it possible to change the feel of real-world surfaces and objects, including touch-screens, walls, furniture, wooden or plastic objects, without requiring users to ...

(Phys.org) -- As time passes and more research is done, more evidence is compiled supporting the theory that suggests that dark matter is a real thing, even though no direct evidence for its existence has ever been found. ...

Over the past decade, scientists have found evidence of hundreds of planets orbiting stars outside our solar system. A group of volunteers has also joined the search, and they have found several additional planets that initially ...

Atherosclerosis, resulting in a narrowing of the arteries and the development of cardiovascular disease, is the leading cause of death worldwide. Until now, no treatment could target diseased areas exclusively, in order to ...

Evolution by definition is cold and merciless: it selects for success and weeds out failure. It seems only natural to expect that such a process would simply favour genes that help themselves and not others. Yet cooperative ...

(Phys.org) -- This image from the Hubble Space Telescope shows planetary nebula NGC 7026. Located just beyond the tip of the tail of the constellation of Cygnus (The Swan), this butterfly-shaped cloud of glowing gas and dust ...

(Phys.org) -- Because astronomy and astrophysics are still so much a mixture of theory, conjecture and generally difficult to measure phenomenon, at least as compared with many of the other sciences, one of the most highly ...

Phenomenon

A phenomenon (from Greek φαινόμενoν), plural phenomena, is any observable occurrence. Phenomena are often, but not always, understood as 'appearances' or 'experiences'. These are themselves sometimes understood as involving qualia.

The term came into its modern philosophical usage through Immanuel Kant, who contrasted it with noumenon (for which he used the term Ding an sich, or "thing-in-itself"), which, in contrast to phenomena, are not directly accessible to observation. Kant was heavily influenced by Leibniz in this part of his philosophy, in which phenomenon and noumenon serve as interrelated technical terms.
